My friends have recently become parents for the first time, and among the myriad of new things they both now worry about, whether their baby is too hot or too cold is one of the biggies. A safe sleeping environment can be vital for reducing the risk of cot death (SIDS) and it is currently recommended for the nursery temperature to be maintained between 16–20°C. The Groegg 2 is a wonderful idea that allows parents a quick visual of the nursery temperature with a unique colour-changing room thermometer that doubles up as a nightlight.
